I would like to use the 75/300 in a boat application. We now use a Plettenberg NOVA15 with the Plettenberg MST 60-290 controller and I think the motor can run more efficient with the VESC controller. As well as more option for controlling the motor (like speed control). Is the 3d file for the aluminium casing available so we can convert it to liquid cooling? I think this would be better to attach another aluminium block to the standard housing.
And the second question: is the aluminium housing connected to ground or is it electrically floating?
